SPECIFIGATION forming part of Letters Patent No. 748,965, dated January 5, 1904. Application filed September 17, 1903 Serial Ila-173,52 6. (No model.)

To all whom it may concern:

Be it-known that I, LUCIUS O. MATLAOK, a

following is a specification.

My invention contemplates a novel form of niturein general,but more particularly adapted for use in connection with chairs.

In a furniture-tip characterized by my invention the metallic head which contacts with the floor is composed of upper and lower parts having their edges or perimeters suitably secured together, the upper part consisting, essentially, of a flat disk perforated at its center, and the lower part consisting, preferably, of a cup-shaped portion, whereby the top or upper surface of the said head presents a flat or practically fiat seat for the bottom of the rubber cushion which is interposed between the head and the furniture and whereby the nail-head or enlarged lower 7 end portion of the shank by which the tip as a whole is secured to the furniture is adapted to move up and down or play in the inclosed chamber provided between the lower surface of the said disk and the upper concave surface of the said cup-shaped portion, it being understood that the I said shank extends through and slides up and down in the perforation in the center of the said disk and also extends through and works in the central opening of the said ring like rubber cushion. The nature and advantages of my invention will, however, hereinafter more fully appear.

In the accompanying drawings, Figure 1 is a perspective of a chair having its feet provided with my improved furniture-tips. Fig. 2 is a vertical section through a chair-leg having its lower end equipped with one of of my improved tips. Fig. 3 isa perspective of the rubber cushion involved in the construction of my improved tip. Fig. 4 is a perspective of the metal head and shank involved in the construction of my improved tip. Fig. 5 is a perspective of the metal disk which constitutes a part of the metal head and which serves as the means for connecting the head with the shank. Fig. 6 is a perspective of the cup-shaped portion of the metal head.

Fig. 7 is a perspective of the shank or naillike portion of the tip, which is driven into the chair-leg.

As thusillustrated the tip is secured to the foot or lower end of the chair-leg A. The

1 said tipcomprises a rubber cushion B, which is interposed between the chair-leg and the metal head 0 and which encircles the shank D. It is thesaid shank which constitutes the means for attaching the tip to the chairleg. Preferably the metal head C comprises a disk-like portion 0, provided centrally with an aperture, and a lower cup-shaped portion 0. These two parts are secured together by pressing overthe perimeter of the cup-shaped portion 0'. The shank D extends through the central opening in the disk 0, and its inner end is headed, so as to prevent it from being pulled out. The depth of the cupshaped portion 0' determines the amount of play or lost motion existing between the head 0 and the shank D.

In applying the device the shankis driven like an ordinary nail into the chair-leg and to an extent sufficient to slightly compress the rubber cushion B. This cushion in expanding then pushes the head 0 outwardly until the disk 0 bears tightly against the head at of the said shank. Thus applied, the tip constitutes a device for cushioning the lower end of the chair-leg, the cushion B being compressed more or less by any weight which may be imposed upon the chair, and it will be seen that it is this play or lost-motion connection between the shank and the head which permits the rubber cushion to perform its function of cushioning the lower end of the chair-leg.

The disk 0, which constitutes the means for connecting the shank with the head, is an important feature of my invention. It is this feature of the construction which insures strength and durability and which renders it possible to employ a lost-motion connection between the shank and the head Without danger of breakage. proved furniture-tip gives an efficient and satisfactory cushioning and is at the same time very strong and durable and not likely to break or give out.

What I claim as my invention is- In other words, my im-' 1. A furniture tip comprising a shank adapted to be driven into the furniture, a head composed of rigidly-connected top and bottom portions, the said bottom portion being cup-shaped and having its perimeter pressed over to secure the flat disk-like top portion in place, the said top portion having a sliding connection with the said shank, thereby adapting the head to relatively slide up and down on the shank, and a rubber cushion encircling the said shank and adapted to bear against said head, said cushion yieldingly opposing relative upward movement of the head upon the shank, the said disk-like portion providing a flat or practically flat seat for the bottom of the cushion, and the said shank being provided at its lower end with an enlarged portion adapted to move up and down or play in the inclosed chamber provided between the lower surface of the said disk-like upper portion and the concave upper surface of the said cup-shaped lower portion.

2. A furniture tip comprising a shank adapted to be inserted in the furniture, a metal head having a sliding connection with said head, thereby adapting the head to relatively slide up and down on the shank, said head being composed of an upper flat disklike portion and a lower cup-shaped portion, the two portions being suitably secured together or united at their edges, and a rubber cushion encircling the said shank and adapted to bear against said head, said cushion yieldingly opposing relative upward movement of the head upon the shank, the said disk-like portion providing a flat or practically flat seat for the bottom of the cushion, and the said shank being provided at its lower end with an enlarged portion adapted to move up and down or play in the inclosed chamber provided between the lower surface of the said disk-like upper portion and the concave upper surface of the said cup-shaped lower portion.
